When you are using a grow tent to grow indoors, humidity is an important factor to take into consideration and manage proactively.
In order to get the largest yields and best-looking foliage and blooms, humidity is essential and needed for all plants to grow efficiently and reach their maximum potential.
You want to be able to manipulate this factor so that it fits the required humidity level for your plants and maintains control of the environment.
But, what if you only have a grow tent? Can you control, or even increase its humidity?

How to increase humidity in a grow tent?
To increase your grow tent’s humidity, you can start mixing plants of different ages together. Another way is to add water to the grow tent itself. You can also lessen the lights and fan speed to aid in bringing more humid air to your plants. Otherwise, simply buy a humidifier.
Ways To Increase Your Grow Tent’s Humidity
It is important to note that the humidity in your grow tent can be manipulated and increased to match the needs of your plants.
If you have low humidity inside the grow tent for long periods of time, your plants will not grow as quickly, making them shorter physically and in their lifespan.
There are several ways that you can safely increase the humidity in these grow tents and control the growing conditions around your plants.
Start Mixing The Plants
Without having to include too much labor, you can mix your plants by their age in order to manipulate the humidity within the grow tent.
If you mix together larger plants next to the smaller plants, you can expect the humidity levels around these smaller plants to rise, allowing a healthy and growing environment where they will want to catch up to the mature plants.
Add Water To Your Grow Tent
In order to create a humid environment, your grow tent needs additional water in the area.
When you add tubs of water in the grow tent near the plants, the air will absorb the water, creating a stronger humid environment for the surrounding plants.
You can also add water by hanging drenched towels around the grow tent. As the air flows in, the water will evaporate and fill the air as it disperses around the plants.
If you do not have towels, you can use a spray bottle filled with water and spray along the tent walls around the plant.
Install A Humidifier
One of the best tools you can purchase to manipulate any area is a humidifier.
It adds the appropriate water level to the air, making it more comfortable for those who have trouble breathing.
Adding this to the grow tent allows a more moist air content, essential for the growth of your plants.
When you purchase a humidifier for your grow tent, you should make sure that it is compatible with the size of your tent.
The water tank and the area to be covered must be proportioned so that you can adequately humidify the area within.
With a humidifier, you are able to increase or decrease the humidity in order to get the air to the right water consistency.
Reduce Lights and Fan Speed
Since an increased presence of heat is known in most environments to absorb the air, drying it out, then you may want to reduce the number of lights that are in your grow tent.
While lights are important to the growth of these plants, it is also important to find an appropriate balance between heat and humidity.
Blowing your fan constantly can also negatively impact the humidity in your grow tent.
With it blowing at a high speed, the water in the air will evaporate quickly, drying out your plants and affecting the overall yield.
Too slow of a fan speed will also be ineffective in distributing the humid area to all of the plants in the grow tent.
A medium speed is often the best choice to move the air around without drying it out.
Too much humidity and its effects
If you find that you are very good at creating humidity for your grow tent, you do not want to overdo it.
If you attempt to use all of these different changes at once, you could cause too much humidity in your grow tent.
For some plants, you can negatively affect the roots and keep them from absorbing the appropriate water for proper growth.
Too much humidity also makes way for mold, fungus, and bacteria to develop in your grow tent.
Depending on the plant, this could be terminally damaging and spread to your other plants.
Reasonable humidity level
Depending on what type of plants you have and where they are in their growth determines how much humidity you need.
If you have a grow tent full of seedlings, then you want your humidity a little higher around 70 percent. Much higher than this and you can expect mold and bacteria to begin developing.
If you have ornamental plants and flowers that you will be planting later, then you can keep your levels around 50 percent once they have started growing steadily.
Moving Forward With Humidity
Once you start your grow tent and bring in the seedlings and plants, it is important to know what type of humidity level you need in the grow tent so that you can begin generating that level early on.
Depending on your local environment and the location of your grow tent, what works for you may be different for someone else.
Take the local factors and environment into consideration and then begin working to manipulate the humidity to fit your personal needs for your plants and generate the biggest yield possible.
Cost Of Increasing Grow Tent Humidity
Most of the ways to increase humidity in your grow tent involve using everyday tools and items you have in your home.
The biggest purchase you may make for your grow tent is the purchase of a humidifier.
This is an investment to make if you have lots of plants in your grow tent, or you have exhausted all other options, and it just is not enough to keep going.
